How to prevent self update of HU

[makemyday]

Hello, I hope someone can help me here.

Today I saw that an update of PatchMyPC Home Updater was installed on my 4 PCs on 26.03.25 at 7:00 p.m. (the latest version 5.1.1 on each).
PatchMyPC wasn't even started yesterday, so the installation must have been running quietly in the background. (Also, the program was installed in the default directory, but I actually used a different installation path)

How can I prevent PatchMyPC from running in the background and updating silently in the background?

I definitely want to update PatchMyPC manually when I see a new version is available.
 
Where is this controlled and what can I do about it?
